Overview
Sony's SRS-XB100 is a super-compact Bluetooth speaker with an IP67 waterproof and dustproof rating, a carry strap and up to 16 hours of battery life. It charges over USB-C and includes a microphone for hands-free calls.
The XB100 is built for portability first, trading larger sound for a size that fits in a bag or cupholder, with Sony's sound diffusion processing meant to spread audio wider than the small cabinet would suggest. IP67 covers both dust and full submersion, which is a step up from splash-resistant ratings on cheaper mini speakers.
- IP67 waterproof and dustproof
- 16 hour battery life
- USB-C charging
- Stereo pairing with a second unit
Who it's for
Good for someone who wants one small, rugged speaker to bring to the pool, beach or campsite without worrying about water or dust. Not the choice for anyone wanting deep bass or room-filling volume, since the compact size limits output.
Pros and cons
- IP67 rated for dust and full submersion
- Up to 16 hours of battery life
- Compact with a built-in carry strap
- Can stereo pair with a second XB100
- Small size limits bass and overall volume
- Not intended as a primary home speaker
Performance notes
The IP67 rating means it can survive dust exposure and temporary submersion, backed by a UV coating for sun exposure. Two units can be stereo paired for wider sound, and the built-in microphone with echo cancellation handles hands-free calls through the Bluetooth connection.
